One of the worst things you can do is to realize you have left out something or forgotten an important detail just before you board a plane to the United States.

Travelling today is a little bit technical due to issues of global terrorism, changing weather patterns and country specific restrictions that have to be adhered to.

To travel safely and comfortably, Hotels-Fairy.com has compiled a brief guide with the most important things you need to know before travelling to the US.

So here are a few things you might want to check out.

Delays could happen

Remember if you are travelling in winter snow storms could bring about cancellations and delays across the main airline hubs within the US. Before travelling, you might want to contact your airline or travel company to prepare accordingly. You can also monitor the US airport conditions online, such as through the Federal Aviation Administration site.

Do not forget that the US hurricane season usually begins from June all the way to November and it is capable of affecting the coastal regions of the United States.

Medical Cover

Almost 4 million people from Britain visit the US annually and while the visits are usually without any trouble, you might want to get yourself a comprehensive medical and travel cover before travelling. This is very important because anything could happen while in the New World.

Valid travel documents and details

Before you travel to the United States ensure that your passport, Visa or any other travelling document is valid and has not expired. If you are from the UK and other 37 Visa Waiver countries you can easily enter the United States without a valid US visa for three months or 90 days.

The Visa Waiver Program allows you to visit the US for tourism or business reasons and you do not have to wait until a valid visa has been granted. However, as one of the citizens in the Visa Waiver countries you need to apply for ESTA (Electronic System for Travel Authorisation) to be allowed to enter the country.

Citizens of other countries outside the Visa Waiver nations must apply for valid US visa to be allowed entry.

Travellers from risky regions

It is worth noting that travellers arriving from countries affected by Ebola in West Africa, particularly Sierra Leone, Liberia and Guinea should arrive at any of the five main airports so that they can undergo proper health screening. While this can change, it is always important to clarify and counter check before you travel.

Car hire

If you are planning to hire a car in the US to save time and money that you could have used in public transport and taxis, make the arrangements before you board the plane. Renting a car prior to travelling can help you save money and time, especially if done online due to immense deals offered to travellers.

Specific requirements

If you have unique requirements that might complicate your travelling or your health it is important to notify the airline as soon as possible. This could save you a lot of trouble as well as incurring losses while in America, which you could have avoided with a little planning.

Above all, you might want to remain as safe as you can and observe caution. Even in a great country like the US something negative could happen at any moment as history has shown.
